One passive crossover board per speaker, so build two. Single-sided, through-hole only, CNC isolation-milled with an 0.8 mm end mill (the DTU 62768 process). The topology is the PrintYourSpeakers reference crossover, unchanged; only the component values are substituted for what the DTU component shop actually stocks.

Status: schematic done (ERC 0 violations), board routed by hand on B.Cu, 144.5 × 110 mm, four M4 corner holes, DRC clean. Mill and laser files are in production/illuminate7mk2-crossover/ (Gerbers + Excellon for the CAM, silktop.dxf` for the laser silkscreen). Coils: L102 may be…
